| titleOfInvention | APPARATUS FOR NON-INVASIVE INTRACRANIAL SURGERY BY THERMAL ABLATION THROUGH AN ARRANGEMENT IN POLYHEDRO-SEMIESPHERIC PHASES OF FLAT ULTRASOUND TRANSDUCERS. |
| abstract | The present invention refers to an apparatus for non-invasive intracranial surgery by thermal ablation by means of a polyhedron-hemispherical phased arrangement of ultrasound-generating plane transducers, of the type comprising: a power source, a multi-channel signal generator, an array of ultrasound transducers, and a deformable water-filled membrane as an interface between the transducer array and a patient's head. The array of ultrasound transducers is characterized in that the array is polyhedron-hemispherical and in which the vibrating surface of each of the transducers is flat with polygonal geometry, of equal or approximately the same surface area. The geometric center of the plane that describes the vibrating surface of each transducer is tangent at a point to the sphere described by the principal radius of the array, which is measured from the center of the sphere to the center of the plane that describes the vibrating surface of each transducer. The principal radius of the array is greater than the distance measured from the geometric center of the array to the surface of the patient's skull. The principal radius of each and every transducer is the same length. The transducers are separated from each other by an acoustic wave absorbing material, which has a hemispherical configuration with a radius greater than the main radius of the arrangement, therefore the arrangement is called polyhedron-hemispherical. By operating two or more transducers with a frequency between 0.5 and 1 MHz and a total acoustic power between 650 and 2624 W, the device generates high intensity focused ultrasound, the acoustic waves of which pass through the patient's skull and propagate through the brain tissue produces a high acoustic pressure within a spherical focal region, which in turn generates a high acoustic intensity which produces a temperature increase above 55 ° C sufficient to thermally ablate the brain tissue. |
